Q

It is the original hard drive. These are magnetic storage devices that have been around since the 1950s though they’ve evolved over time.

A

The Hard Disk Drive (HDD)

19
Q

Emerged far more recently in the mid-90s ______don’t rely on magnets and disks, instead they use a type of flash memory called NAND.

A

Solid State Drivers (SSD)

20
Q

Also known as volatile memory chips because they lose memory once the power supply is removed. __________ can only transmit a single line of memory and needs to be constantly refreshed to prevent the loss of memory bits.

A

Dynamic random access memory (DRAM)

21
Q

Non-volatile chips that are commonly used in portable battery-powered devices. Unlike DRAM, they do not need to be refreshed and do not immediately lose memory when the power source is disconnected.

A

Static random access memory (SRAM)

22
Q

Mainly used when memory is being transferred between different types of devices.

A

First in, first out (FIFO)

23
Q

The memory in these chips can be erased when exposed to ultraviolet rays. These chips can then be reprogrammed for a new set of data values.

A

Erasable programmable read only memory (EPROM)

24
Q

Differs from other programmable memory chips as they can only be programmed once. The contents cannot be erased electronically or though ultraviolet rays.

A

Programmable read only memory (PROM)

25
Q

It is an operating system feature that enables the computer to compensate for the lack of physical memory by transferring data from random access memory to disk storage.

A

Virtual Memory

26
Q

It is a process by which computer programs and services are assigned with physical or virtual memory space.

A

Memory Allocation

27
Q

It is an integral part of the computer hardware which stores information/data to process the result of any computational work

A

Storage Device

28
Q

It is also known as internal memory and main memory.
This is a section of the unit system that holds program instructions, input data, and intermediate results.

A

Primary Storage Device

29
Q

It is used to store information that is used immediately or we can say that it is a temporary memory.

A

RAM (RANDOM ACCES MEMORY)

30
Q

The data written or stored in these devices are non-volatile, i.e, once the data is stored in the memory cannot be modified or deleted.

A

ROM (READ ONLY MEMORY)

31
Q

Is a memory that is stored external to the computer.
It is mainly used for the permanent and long-term storage of programs and data.

A

Secondary Storage Devices

31
Q

Primarily hard disks, are widely used to store computer data as well as audio and video signals

A

MAGNETIC STORAGE DEVICE

32
Q

It is a card in which data is stored by modifying or rearranging the magnetism of tiny iron-based magnetic particles present on the band of the card.

A

MAGNETIC DISK

32
Q
  • is a long-life and non-volatile storage chip that is widely used in embedded systems.
  • it can keep stored data and information even when the power is off.
A

FLASH MEMORY DEVICE

33
Q
  • It is also known as a USB flash drive that includes flash memory with an integrated USB interface.
A

PEN DRIVE

34
Q
  • a mass storage device like HDD.
  • has 10x faster read and writes speed as compared to hard disks.
A

SSD (SOLID STATE DRIVE)

35
Q
  • It is generally used with electronic devices like phones, digital cameras, etc. to store larger data.
A

SD CARD

36
Q
  • is any storage type in which data is written and read with a laser
A

OPTICAL STORAGE DEVICE

37
Q
  • It contains tracks and sectors on its surface to store data.
A

CD (COMPACT DISK)

38
Q

Are circular flat optical discs used to store data.

A

DVD (DIGITIAL VERSATILE DISC)

38
Q

Just like CD and DVD but the storage is e capacity of blu ray is up to 25GB.

A

BLU-RAY DISC

39
Q

Computer instruction or data, anything that can be stored electronically is a _________?

A

Software

40
Q
  • refers to the low-level software that manages and controls a computer’s hardware and provides basic services to higher-level software. Systems software includes the programs that are dedicated to managing the computer itself, such as the operating system, file management utilities, and disk operating system (or DOS).
A

System Software

41
Q

Actually the ______________ consist of programs that are designed to make users more comfortable or productive to assist personal tasks.

A

Application Software

42
Q
  • Is made available to every one and can be change, modify and distribute to public without any notification.
  • Ex. Linux, Moodle, WordPress, Drupal and etc.
A

Open Source software

43
Q
  • is the software that is freely available to public but author has a copy right, means that you can only use it, not sell it.
  • Ex. Anti-Virus
A

Free ware

44
Q
  • An ______________ is software which manages computer hardware and software resources. It also provides common services to computer programs
A
